PSST special issue征稿 Plasma Sources Science & Technology 面向等离子体数值模拟开展征稿，征稿主题为： “Verification, Validation and Benchmarking of Low-Temperature Plasma Models” (1) Verification: A comparison of simulations and analytical solutions to test the intrinsic consistency of a model (2) Validation: A comparison of simulations with experimental results or observations (3) Benchmarking: A comparison of two or more models under the same conditions, but with different numerical implementations or on different scales (like particle or fluid models) 截止日期：2022年12月1日 网址： https://iopscience.iop.org/journal/0963-0252/page/Special-Issue-on-Verification-Validation-andBenchmarking-of-Low-temperature-Plasma-Models 甜点：进展一瞥 脉冲等离子体持续生产NOX：低能耗背后的化学机制 （安特卫普大学） https://doi.org/10.1039/D1GC02762J 文章展示了利用空气放电高能效产生NOX的能力，其能耗仅为0.42 ± 0.03 MJ/(mol.N)，是迄今为止等离子体生成NOX所需的最低能耗。实现该低能耗的关键是脉冲功率和温度。
饮料：职业机会 Post-doctoral Fellow in Computational Plasma Physics, West Virginia University, USA The Department of Physics and Astronomy at West Virginia University (USA) is seeking applicants for a Postdoctoral Fellow in computational plasma physics, with an emphasis on a collaboration with an in-house solar- and space-relevant laboratory plasma experiment. The ideal candidate will work with Profs. Paul Cassak, Weichao Tu, and Earl Scime to use an existing particle-in-cell code with boundary conditions representing the laboratory experiment to model magnetic reconnection in kinking flux ropes in the experiment, and to run test particle simulations with an existing code to study particle acceleration in electromagnetic fields in the experiment.
